To all whom it may concern:

Be it known that l, ARTHUR KArsER, a citizen of the United States,residing in the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in a CombinedPrinting-dachine and EnlargingeCamera; and l do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it apertains to make and usethe same, reference eing had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in apparatus adapted for use byphotographers.

My object is to provide a single apparatus which may be so modified byadjustment that it shall be adapted for use by the photographer for allpurposes after the negative has been taken.

The invention is therefore a sort of combination apparatus which may beemployed as an enlarging camera, and printing machine, a retouchingstand and a copying camera.

The invention will now be described in detail reference being made tothe accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure 1 is a sectional view illustrating the combinedapparatus shown as an enlarging camera. Fig. 2 is a front view of theapparatus or a view looking in the direction of the arrow in Fig. 1.Fig. 3 is a section taken through the printing apparatus or machineshown in position for use with the bellows removed. Fig. 4 is a sideelevation of the printing apparatus detached from the frame. Fig. 5 is aperspective view of the retouching frame. Fig. 6 is a front view of theframe for holding the negative located at the end of the casing in whichthe lens holder slides when the device is used as an enlarging camera.Fig. 7 is a section taken on the line 7-7 Fig. 6. Fig. 8 is a sectiontaken through the printing apparatus on the line 8 8 Fig. 4,illustrating the vignetter, the latter being partly broken away.

printing frame 6 g a red curtain 7 and an interposed vignetting frame 8and apertured plates 8A on opposite sides of the frame 8 for the purposeof diffusing the light.

As shown in Fig. 3 the printing apparatus is arranged for contactprinting or printing directly from a negative which is designated by thenumeral 9. Back of this negative is the sensitized paper 10 upon whichthe picture is printed; while 12 is the back or cover for the paperduring the printing operation. This cover is composed of two members 13and 14 divided in a longitudinal direction and connected by hinges 15.

The printing frame proper is designated 16. A transverse bar 17 iscomposed of two inembers 18 and 19 hinged together as shown at 20. Themember 19 is hinged to the frame at 21 while its opposite extremity isadapted to engage a spring-actuated keeper 22. Connected with the member18 of the bar is a bow-shaped spring 23 while a similar spring 24 isconnected by means of screws 25 with the member 14 of the hinged cover.These screws pass through slots 26. The member 18 of the cross bar isconnected with the member 13 of the cover by wire or small rod 27passing through a loop 28 of the bar and connected at its extremitieswith the cover member on opposite sides of the bar. This printing frameis connected with an auxiliary frame 29, by means of pivoted catches 30at the top and bottom. The curtain 7 is connected at the top with aspring roller 32 by means of pieces of tape 83, one being connected ateach side of the curtain. The upper extremity of the curtain is providedwith a transversely disposed solid strip 34 which forms a stop toprevent the curtain from winding upon the roller. This curtain isconnected at its lower extremity with a roll 35. A cord 36 is connectedwith the lower roller and adapted to wind upon one extremity thereof. Bypulling this cord which passes over guide pulleys 37 and 38, theoperator may pull down the curtain and allow the light to pass to thenegative 9 for printing purposes. By means of this curtain arrangementthe printing of pictures from negatives may be very rapidlyaccomplished. By employing a rock shaft 39, a foot lever arm 39A and arod 40 adapted to be operated by the foot as shown in Fig. 1, theprinting may be carried on with great rapidity since only a shortexposure is necessary in order to print the picture 5 and by virtue ofthe special construction of printing frame heretofore described, thework of printing is greatly facilitated..

During the operation of priming negatives from actual contact, theprinting apparatus heretofore described is preferably placed in theposition shown in Fig. 3 in which it is inclined to such an angle as toallow the negative to maintain iis position within the printing frameproper by gravity. ln order to so mount the printing apparatus, theauxiliary frame 2), is mounted upon an outer frame lil. by means ofspring' catches 4t2 at the bottom and a spring-aetua' ed boit 43 at thetop.

then it is desired to produce an enlarging camera, my improved printingapparatus connected with the frame LtlV as heretofore explained, isslidably mounted upon `the base plate all, the mechanism occupying avertical position and being slidable in wajlfs t5 formed upon the said.base. Between Ithe frame plate 4l and an opposing bact'. plate 416, isinterposed the bellows -l connected with a frame i8 which is secured tothe frame plate -Lti by means of pivotally mourned latches i9 fastenedto the bars 50. These members 49 overlap the llanges 8^ l' the bellowsframe thereby locking said frame in the position shown in Fig. il. Thel'fars 5() act as stops to prevent the frame -l-t from having a verticalmovement. rthe opposite extreniityr of the bellows, is connected withthe back plate a6; while the lens holder 5i is mounted on a telescopingframe located in an outer casing At the rear extremity of the casing 53is located a negative 54radj'ustably held in place by springs 55.

The size of the picture is obtained by the adjustment of the lens holderVwhich telescopes in the casing 53 as heretofore described. After thesize has been determined, the proper focus is obtained by moving theprinting apparatus by sliding the plate -il upon the base Llef. As soonas the proper focus is obtained, the ground glass plate is removed and aplain glass plate 56 is placed in its stead (see Fig. i). In this casethe glass plate 56 takes the place of the negative when printing fromdirect contact as illustrated in Fig. 3. it must then be understood thatin Fig. 1 the part designates a plain glass plate while the negative 54is located at the rear extremity with the casing 53 in which the lensholder telescopes. rlhe apparatus disclosed in Fig. i then becomes anenlarging and printing camera. rl`he proper enlargement having beenobtained in the manner just explained, the printing then goes on in thesame manner as heretofore described when printing' from direct contactwith the negative. rlhat is to say the cover of the printing frame isopened, and the sensitized paper placed upon the glass plate 56. Thecurtain 7 is then, drawn down in the manner heretofore explainedandfheld in this position during the short time taken for printing.ri`he curtain is then allowed to return to its normal positionautomatically. 'if he printed picture is then taken out and anotherpiece of paper put in place and thus the work goes on with exceedingrapidity as heretofore explained. Vv'hile adj usting the printingapparatus upon the base la in order to get Vthe proper focus, a thumbnut 57 and a bolt 58 are employed.. By loosening the thumb nut theprinting apparatus may be moved in the one direction or the other uponthe base as until the proper focus is obtained, after which the thumbnut is tightened and the work of printing goes on.

rl`he plate il is provided with screw bolts 70, which enter aperturedangle plates 7]. When it is desired that the printing` frame be held inthe vertical position the bolts 7() after passing through i he aperturedangle plate Tl receive thumb nuts 72 whereby the frame is locked in thedesired position. The frame after being adjusted to the verticalposition as above described may also be secured in place by the lockingmembers 73 passing through slots 74; formed. in the telescoping parts 75shown in -lfig. i.

when printing' from direct contact7 the printing apparatus s held in theinclined position by approximately triangular side members 5t).

For retouehing purposes, the entire printing apparatus is removed and aboard 6() put in the place of the member 29. The negative 6i is thenmounted upon this board for retouching purposes.

rl`he ,mechanism shown in Fig. 2 of the drawing is for the purpose of(,letermining the condition of the worli in the machine which is done bymerely opening the portion i3. This avoids the necessity of removing theentire frame 29 and other' parts of the camera as is necessary in olddevices.

Having thus described my invention, what l. claim is:

l, in a structure of the class described, the combination ot a printingframe, two rollers occupying a position in the rear of the printingframe, one in a plane above the other, a red curtain connected with onei'oller and adapted to be wound thereon when the latter is rotated, theother roller being a spring roller and being connected with oneextremity of the curtain, flexible devices adapted to wind on the springroller, the upper end of the red curtain being provided with a stop tolimit the winding movement of the spring roller as soon as the stop onthe curtain has reached said roller, substantially as described.
